Perhaps there could be a graph that shows which species spreads a virus best? That is, how many times, when the bot fires a virus, does the virus infect another bot? This could be customizable to order it by multiple variables such as how many get infected or how many get infected in the smallest amount of time. This way, you could find out what species spreads the virus the quickest. Or you could have something like the Best Bot, but instead call it the Best Virus Spreader. But that might take up a lot of memory, recording how many times a virus infects or decays.. so.. I dunno. It's just an idea.
